METAL FRAME AND STOCK THEREFOR.

SPEGIFIO'ATION forming part of Letters Patent No. 539,318, dated May 14,1895.

I Application filed February 26, 1895. Serial No. 539,664- (No model.)

To all whom it may concern.-

Be it known that I, ALBERT. WANNER, J r., of Hoboken, in the county ofHudson and State of New Jersey, have invented new and usefulImprovements in Metal Frames and Stocks Therefor, of which thefollowingis a full, clear, and exact description.

The invention relates to the manufacture of metal frames, especiallyframes for mirrors, stands or plateaux for vases and the like, and forpictures, and the object of the invention is to produce a stock ormaterial that may be bent into the form of a frame without buckling orbending irregularly, and further, to produce cheap and ornamental framesof the general character mentioned.

The invention consists in the novel features hereinafter particularlydescribed and defined in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure l is a broken side elevation showing a piece of my improved stockor material for the manufacture of frames. Fig. 2 shows a cross-sectionof such stock. Fig. 3 is a plan View of a stand or plateau framedinaccordance with my invention, and Fig.4 is 'a vertical section thereofon the line 4 4 in Fig. 3.

In practice my improved stock is made up in convenient lengths, and itconsists of a strip a of flexible sheet-metal which is shaped at oneedge to give it in cross section a concavo-convex conformation, it beingunderstood that the lines may not be true curves. The concave-convexformation is so produced that 'it first departs laterally at one side ofthe flat body a to form a rounding shoulder or overhang b, and is thenreturned on itself on rounding lines, as at c, the free edge 11 forminga shoulder or overhang disposed in the opposite direction, as willappear from Fig. 2.

Usually I form circular frames from this stock, as illustrated in Figs.3 and4, and in the bending of the stock to curved shape, theconcavo-convex edge "supplies the necessary fullness of material tocompensate for and yield to the changing form of the strip, and therebyavoids irregular bending or kinking, whereby a frame is readilyformedwithout irregularities. When shaped the frame re-' ceives legs e, whichare secured to the exterior of the band a and the points of connectionare covered by the outer overhang or shoulder I). Also there are securedexterior] y on the strip a a series of retainers f, which are bentinward and shaped so as to afford a proper contact with the mirror orits equivalent g, or the backing g thereof, and the points of connectionof the retainers with the strip a are also overhung by the outershoulder b.

It will be seen by reference to Figs. 2 and 4, that the loop formed bybending one edge of the strip is an open semicircular loop, the spacebetween the inner shoulder 01 and the body a of the strip receiving theedge of the mirror g, and the shoulder at terminating above the bend bso as to form a stop engaging the said mirror at a point inward from itsedge, as appears clearly in Fig. 4.

Having thus fully described my invention, I claim as new and desire tosecure byLetter-s Patent.

1. The herein-described stock for the manufacture of frames andthe'like, the same consisting of a flexible narrow strip having at oneedge a lateral bend forming a shoulder, and beyond said bend a secondlateral bend in the reverse direction to the first-named bend, the freeedge terminating above the first-named bend and being spaced from thebody of the strip, forming an open, semicircular loop and providing ashoulder in a higher plane than the first-named shoulder and at theopposite side of the body, substantially as described.

'2. As a new article of manufacture, a metallic frame, comprising a bentstrip having along one edge an outward and an inward bend, substantiallyas described.

3. As a new article of manufacture, a metallic frame, comprising a bentstrip having along one edge an outward and an inward bend, overhangingthe body of the strip, and legs secured exteriorly on the strip, thepoints of connection of. the strip being overhung by the outward bend,substantially as described.
